Guide techniques for raising crickets at home - healthy crickets - fast for harvesting

Crickets are increasingly being raised at home because of their high economic value. The technique of raising crickets is not too difficult, so you can rest assured. Besides, crickets have good reproductive ability, so the profit is very good.

How to raise crickets

So let's learn how to raise crickets to get high economic value!

1. Guide to raising crickets for high productivity
1.1 Preparing the environment for raising crickets
Breeding barn

No need to be too fussy, the cage of the crickets can be a bucket, a brass, or an old pot with a lid. But you need to make sure they are quiet and cool.

The lid can be an old bowl or lid with many holes perforated to create ventilation. Opened during the day, closed at night to prevent crickets from flying away as well as cats or mice catching crickets.

Before releasing crickets, cages need to be washed and dried to serve livestock. Depending on the conditions and means of rearing that you arrange accordingly.

Breeding crickets like their parents (this type is forced to spawn) in a tank with a capacity of 40-50 liters, 10 male crickets and 20 fish crickets can be released. In 80-80 tanks, 30 female crickets and 15 male crickets can be raised.

Cricket farming techniques
Livestock equipment

Bamboo troughs, laying troughs or feeding and drinking troughs for crickets need simple. You can also use clam shells or make them from cement or crockery. The size of the devices does not need to be too large to prevent the baby crickets from falling and dying. (about 10 to 15cm in diameter, about 1.5 to 2cm thick and about 0.5 to 1cm deep.)

In the cage, you put a bamboo basket with a diameter of 15 to 20cm (the type of basket that holds pots and pans). Crickets must be the type with small holes and thick to feed the newly hatched crickets up to 25 days old. The sparse type is used to raise until maturity and harvest. A 45l bucket can be stacked 10 racks, 40l is 15 baskets.

The baskets are stacked enough to create space for laying troughs, food or water troughs for crickets. The soil placed in the trough must be clean, porous and moderately moist. The ideal thickness is from 3 to 4 cm. Soil you can mix with ground coir. You absolutely must not use soil with ants, soil contaminated with chemicals. The top of the board is covered with a layer of grass for crickets to eat, grow, and reproduce.
1.2 Selection of breeding breeds

Choose big, strong crickets with antennae, wings and legs. You pair them in the ratio of 1 male and 2 female.

Depending on the farming method, you decide the number of seed crickets. In the pot you should put 1 tray of water, 1 tray of soil (for crickets to lay), 2 trays of food and 3 baskets for crickets to sit and climb.


Breed selection
Tips to distinguish male and female cricketsMale crickets will have brownish-black wings, not shiny.
Black, glossy female crickets (smooth look)
Smaller-bellied male crickets.
Crickets have bigger bellies because they have eggs
Male crickets do not have egg-laying troughs.
Female crickets have egg-laying troughs in the tail. The trough is like a sewing needle so crickets can stick to the ground and lay eggs.
Male crickets can call (to court females)
Crickets can't call.
1.3 Cricket food

You can make use of a variety of plants such as grasses, leftover leaves, sweet potatoes, cassava vegetables, papaya leaves, watermelon pulp, cucumbers, etc. As long as the foods are washed and cleaned, Pesticides are okay. The grass must also be clean and free of chemicals.

Food for crickets needs to be guaranteed

In addition, you can supplement the crickets with finely ground bran and make sure the crickets always have clean water to drink. You should use a flower sprayer to spray to ensure enough moisture and place a small tray of water to prevent crickets from slipping and falling dead on the inside. If you raise a large scale, you should use a large capacity tank, spray 2 or 3 times a day depending on the weather.

2. How to raise crickets effectively
2.1 The life cycle of reproductive crickets

Stocking: Apply the ratio of 1 male 2 female. Small bucket stocked 15 males, 30 newly matured females. Large bucket (80l) can release 25 males and 50 females.

Laying eggs: After 2, 3 days of laying crickets begin to lay eggs in the spawning trough

Cricket is about to give birth: You will find it easy to retreat and often pick the needle from the tail to the bottom of the bucket. At this time, just put the trough in and the crickets will lay immediately. And of course, in the trough, there must be clean and moist soil available. When the crickets show signs of being about to give birth, put the laying trough in the nest every night the crickets give birth.

Every night, you bring the litter box to the incubator and in the evening bring a new litter into the bucket to breed again. For every 30 hens, every night, thousands of eggs will be laid in the trough. Crickets that give birth within 2 months are discarded.

Because of the shy nature, you should leave the crib in the evening. Each night put in a litter tray and the next morning take that tray to incubate eggs in another area.


Crickets have a fairly fast reproduction rate
2.2 Incubation technique

The egg incubator is designed as follows:

At the bottom of the bucket, you lay a layer of porous soil about 1cm thick, 3cm wide. Continue to place 3 egg trays in the middle of the bucket and cover it with a thin layer of grass. Every day you spray water 1 to 2 times to keep moisture or before putting the egg tray into the hatchery.

You prepare 2 square face towels (specialized towels for restaurants). Wet it and place it on the bottom of the incubator, then put the egg tray on. Continue to dip the second towel and cover the trough to retain moisture.

When finished, close the lid of the box. Change towels every 3, 4 days to keep moisture. Hatching eggs need a temperature of 25 to 30 degrees Celsius. After 8 to 12 days, the crickets hatch. When you see that the crickets have all hatched, take out the egg tray and transfer the baby crickets to the nursery bucket to raise separately.
In order for crickets to have a lot of babies and healthy babies, it is important to note:

- The cage and farming equipment should be clean and dry. Food troughs must be covered to avoid moldy water, etc. Place the litter in the bottom of the bucket to one side, and place the feed trough, water trough, and stack on the other side. Finally, cover the basket with some fresh grass. Spray water on fresh grass 1 to 2 times a day. Note that it is mist only.

– When the crickets lay 1 day, transfer the egg tray to the incubator and put another litter in the bucket. You can use a thick cardboard box or a plastic tray measuring 60 x 40 x 20 cm to incubate the eggs. Each carton should only hold 8 to 10 egg trays. Pressure bins must be sealed, with a lid (using a mosquito net as a lid is also possible), monitored daily to avoid harmful ants….


2.3 Caring for crickets after hatching
New hatching stage up to 15 days old

From 2 egg trays, goats can hatch about 2000 children.

– You should arrange 1 to 2 baskets to place pots in the crate so that crickets have a place to park, climb, and hide.

– In the pot put 2 to 3 small food trays.

– Because the crickets are still small at this time, you should not put a tray of water in, but only let the crickets drink water by spraying water on the grass or vegetable leaves for the crickets to eat. Or you can also use a cloth soaked in water for the crickets to absorb water.
Cricket stage from 15 to 45 days old

– At this point you can put a tray of water in for the crickets to drink because the crickets have grown, don't worry about drowning. Usually, you should put 1 tray of water and 2 trays of food for crickets. And remember to add a basket for crickets to perch.

– If there are too many crickets, you should separate them into another pot to ensure 1000 children per pot.

– You can add vegetable leaves or clean grass for crickets to eat

– Change the water tray for the basket once a day and change the food tray every 2 days. If you still have bran, throw it away and replace it with new bran. Depending on how fast the crickets eat, you put food in accordingly.

– Every 5 to 7 days, clean the pot once.

Note: When crickets mature, they often fly out at night to find food and sexual activities. Therefore, in the evening, you should close the lid of the bucket and open it in the morning to cool.

3. Disease prevention and cricket harvesting
3.1 Prevention of diseases for crickets

You need to follow the 3 clean motto: stay clean, eat clean, drink clean, especially when changing the living environment or the weather, the more you need to pay attention to good hygiene and care to enhance resistance and fight against disease. stress for crickets.


Domestic crickets often suffer from some diseases, especially intestinal diseases.

Intestinal diseasesCause: It can be due to high density, hot and humid cages or drinking water mixed with feces and food. These things cause environmental pollution or rancid food, unhygienic drinking water.
Symptoms: Crickets are eating and drinking, normal health, but suddenly stop eating and then become weaker. The beard is broken horizontally, the stool is watery, milky and 7 to 10 days later it dies! This disease is very contagious but very difficult to treat.
Prevention and treatment: Prevention is better than cure. Prevention is when you detect the symptoms, it's too late. It is best to keep their lips clean as well as the food and drink that must be changed daily.
3.2 Harvesting crickets

You use a nylon racket to harvest, then put it in a paper box with bamboo baskets and fresh grass so that you don't die when moving. Or you can freeze the crickets after washing them with clean water or 2% saline and put them in a freezer tray.

Cricket care and maintenance is quite simple, with few diseases, but it is easy to bring high economic efficiency and anyone can raise it.
